Most of smart TVs are generally equipped with HDMI ARC port. If your sound system has ARC input, it will allow you to enjoy better performance through a single HDMI cord.
However, many audio receivers have no ARC input, so we need a HDMI ARC audio converter to convert audio signal to home theater system, soundbar or AV receiver with optical, digital coaxial or analog audio input port.
Although we can fine analog AUX or RCA (L/R) stereo interface in some HDMI converter and ARC function, as we known, lots of ARC converters are only available from SPDIF optical output, not available for analog stereo audio. So if your audio speaker only have analog input ports, the only solution is HDMI ARC to analog audio converter (3.5mm AUX/ RCA)
In addition to analog (3.5mm AUX / RCA) audio output, these converters also added the mainstream Optical or digital coaxial audio output, in order to meet the use of various audio.
PS: Most latest HDMI source devices have no dedicated audio output, we can connect it to ARC enabled TV and output audio to most speaker/ home theatre / amplifier / headphone with analog/optical/coaxial input ports through HDMI ARC audio adapter.
The following are the recommended HDMI ARC to Analog converter(s), we will continue to pay attention to it and update more options here.
ROOFULL HDMI ARC to Analog 3.5mm AUX / Optical SPDIF Audio Converter
- Input: 1* HDMI ARC
- Output: 1* Optical + 1* Analog 3.5mm AUX audio output
- Come with 3.5mm to L/R cable to achieve RCA L/R audio output
- Support HDMI ARC (Audio Return Channel) to SPDIF Optical/ Coaxial / analog RCA stereo audio output
- Set audio source format to PCM/LPCM before using because this HDMI ARC adapter does not do Dolby/DTS decoding
